System Administrator

About the Opportunity

TalentoHC is partnering with a leading travel and tourism organization seeking a System Administrator, IT Services to join its global IT team. This role is responsible for the day-to-day administration, support, and reliability of core infrastructure and end-user computing — keeping employees productive across headquarters and global offices. Unlike the cloud/network/security-focused counterpart role, this position is centered on hands-on infrastructure support across VMware virtualization, Citrix Cloud, Microsoft 365, Active Directory/Entra ID, endpoint management, and telephony. The ideal candidate pairs solid technical depth with strong customer service instincts and a commitment to clear documentation and reliable follow-through.

  • Provision, patch, monitor, and maintain Windows Server and select Linux servers on-premises and in Azure/AWS, including backup verification
  • Manage backup and recovery jobs across VMs, Microsoft 365, and file servers; verify successful completion and perform periodic restore tests
• Microsoft 365 & Identity
  • Administer Microsoft 365 services — Exchange Online, Teams, SharePoint, OneDrive — including mailbox management, distribution lists, licensing, and collaboration configuration
  • Administer Active Directory and Microsoft Entra ID — user and group lifecycle, Group Policy, Conditional Access, MFA, and hybrid identity synchronization
  • Manage Windows and macOS endpoints via Microsoft Intune — enrollment, compliance policies, software deployment, patch management, and remote remediation

• End-User Support & Onboarding
  • Provide Tier 2/Tier 3 support for employees across headquarters and global offices via ITSM ticketing system, resolving escalations within agreed SLAs
  • Own IT onboarding and offboarding — account creation, license assignment, virtual desktop entitlements, equipment provisioning/imaging, and timely deprovisioning
  • Support audiovisual and meeting-room technology including Microsoft Teams Rooms and conference room AV
  • Coordinate with vendors and MSPs (VMware, Citrix, Microsoft, Cisco, Dell, Lenovo, Apple, ISPs) for procurement, warranty service, and support cases
• Telephony & Networking
  • Administer 8x8 telephony — user provisioning, call routing, ring groups, voicemail, and call-quality troubleshooting
  • Support Cisco network infrastructure including switches, routers, wireless, and VPN; perform first-line troubleshooting and partner with the network team for changes beyond scope
  • Support core office infrastructure — LAN, Wi-Fi, VPN, firewalls — and maintain reliable connectivity across locations
• Security & Documentation
  • Enforce IT hygiene standards in partnership with Security — MFA enrollment, EDR/AV, encryption, USB policy, phishing remediation, and least-privilege access
  • Perform regular patching and vulnerability remediation across hypervisors, servers, network devices, and endpoints
  • Maintain accurate IT asset records — hardware inventory, software and cloud licensing, warranty tracking, and decommissioning
  • Document procedures, runbooks, and knowledge-base articles; keep documentation current as the environment evolves

Qualifications

• Associate's or Bachelor's degree in IT, Computer Science, Information Systems, or equivalent experience
